I was playing live the other day in a £10 rebuy. I bought in for £10 and had a 2000chip £10 add on. I was on about 5500 chips. play was briefly 6 handed as someone had got knocked out.

Id been getting garbage and looked down at AJoff. blids were 200/400.

I raise to 1200 in mp. Big blind who has about 4500 calls. (he had only sat down about 2 or 3 hands earlier so i didnt know what kind of player he was).

Flop Ac 8h 3s. Potis 2600. He bets 1200. What would you do?
