[hagbard celine]

As played, the shove is fine--at these stakes you'll get called more often by A8, K8, and draws than by sets two pair or overpairs.

However, OP has a background in limit, and it should be pointed out the value of hitting sets in multi-way pots this deep.

99 is on the cusp, but middling pairs like this, this deep, can be very easy to play when you limp them in EP
