| i feel if you check the turn you HAVE to call the river bet in 99% of the cases, but this 19/9/3... hmmm I dont usually add advice maybe due to lack of experience etc. but this is a very odd hand just due to the fact he called your 3bet OOP (so i feel AK here is not in question alot...) AND raised from the SB which usually with a limper means he has at least a decent hand. I feel he calls the flop here alot if he is calling a your3bet preflop since its so dry (which he obv did)... but I really think he would c/c any pair here on the river... so polarized big hand or air, but what would he have that falls under the air catagory with a SB raise and call of 3bet i dont know
looking at it originally i was like, wow obvious call, really thinking about it, im not too sure |
