Captain Shakib Al Hasan and Mahmudullah extended the good start made by debutant Shadman Islam to lead Bangladesh to a solid 5-259 against West Indies on the first day of the second Test in Dhaka.
On a pitch that had little to offer for the fast bowlers, the West Indies spinners bowled 63 of the 90 overs after being sent into the field.
Offspinner Roston Chase had Soumya Sarkar (19) caught by Shai Hope at slip to end a 42-run opening partnership.
Shadman and Mominul Haque looked untroubled until Haque, a centurion in the previous test, was out to a loose delivery by fast bowler Kemar Roach on the stroke of lunch for 29 off 46 balls.
Shadman then received support from Mohammad Mithun, and they combined for a 64-run stand for the third wicket.
Both were out to legspinner Devendra Bishoo, who bowled Mithun (29) and had Shamdan leg before wicket for a patient 76. Shadman faced a national record of 199 deliveries on debut, eclipsing opener Javed Omar Belim's record of 138 balls in 2001 against Zimbabwe.
Captain Shakib held the innings together and established Bangladesh's dominance in an unbroken 69-run stand with Mahmudullah over the last 23 overs.
Bangladesh won last weeks first Test in Chittagong by 64 runs.
