I have around 22000 sitting say top 20 out of 50 left from 500. My opponent had around 27000 blind where 300/600.
ok this one , you have 36bb oop in the sb with QTo i"m guessing this is a low to medium buy in so 3bets are not as effective as the players here are not sophisticated enough for it to work consistently , you need to identify loose/tight passive weak players to your right for it to work better [try to remember who folds a lot to flop/turn bets they are your targets for 3bets and floating]
Do not be a rush to gain chips at 30 to 40bb,be patient and tend to let the good cards come to you.
Do not feel you have to defend a blind just because someone is raising you from the button, you have the button and position in the next hand attempt to steal then.
If you feel that a aggressive opponent is re-raising cont. bets a lot on low boards and using position,then if he calls and you are out of position and you do not hit but have a decent draw try the check raise line and put them to the decision,if you brick out totally do not be afraid to check fold if you have plenty of chips back,there is always other spots to accumulate.
When the blinds are high relative to the stacks and the antes have kicked in be aware of opponents stacks to your left and who are near the push all in stage,there is no need to raise 4x, 2.3bb to 3bb is just as effective for stealing and if your still in the 20bb+ area you can afford to fold to re-raises..iF ANY ACES OR KINGS FLOP and you are the raiser and have plenty of chips , cont. bet everytime use your judgment on the turn as to whether a turn cont.bet is required.
In the end stages medium to high pairs and high cards are more valuable,tend to play these rather than the small pairs and 78s 89s etc that are better early when you are deeper stacked.
If you are in the hi-jack position or later and it has folded round to you, do not limp almost always raise or fold never LIMP, limp only very rarely when there are agressive opponents to your left and you have a monster to trap them with.In the early positions NEVER LIMP if 1st in the pot,IF YOU CANNOT RAISE IT THEN FOLD IT.
If your card dead and cant find spots to gain chips remember patience pays..Also if the table tightens up start raising more from utg utg+1 utg+2 1st in once every 2 to 3 orbits just to help replenish your chips , this can still be a great steal position more so than the button..
So overall i"d suggest just slowing down a little and be patient,there is no need to go out on a fancy dan move,when you are 8 to 12bb that is the time to start shoving..Do not be afraid to fold in the blinds when you are ok chip stack wise.
Start paying attention to the 3 players to your right and there bet patterns and hands shown [play position]and the 2 to your left.[when they are in the blinds,do they defend or donk bet the flop]
There is loads more stuff and a lot is situational and read based, i"m sure the rest will chip in with ideas.Be aware of stack sizes [your own and opponents] and be patient,raise never limp if 1st in,be aggressive,do not feel it is wrong to fold,get a history replayer and play back and review all your mtts..work on that
