30-60 River Decision

[Sparks]

Hawaiian Gardens the other night. I had AKo in the cutoff and raised behind one EP limper, and the SB and EP called. Flop was A T 5 rainbow. SB bet, EP called, I raised and only the SB called. Turn was another 5 and the SB bet. I only called. River was a 2 offsuit and the SB bet, and I went into the tank (well, about 10 seconds, which is the tank in limit). Should I have called?

The SB is a generally solid player, fairly tight, somewhat aggressive, and who bluffs occasionally -- what I consider a "typical" player. After the hand I conducted an instant verbal poll of the table and four respondants said basically "you have to call." No one said a fold was correct.

Were they right? Questionable laydowns on the river are not the way to go, but was this situation really that questionable?

Thoughts appreciated.
